Hi, Tom, the number of scores is given by the actual phrase table and has to be consistent with the contents of the phrase table:
! ||| ! ||| (0) ||| (0) ||| 0.485714 0.377778 0.85 0.772727 2.718 and ||| a ||| (0) ||| (0) ||| 0.765677 0.773064 0.790368 0.85233 2.718 ...there are 5 scores in this phrase table. The max phrase length specifies the maximum number of words within a phrase. The snippet above fits max-phrase-len of 1 but is of course extracted also with any higher limit. There is no other connection between the two values. Cheers, O.
